The 12683 / 12684 Ernakulam-SMVT Bengaluru Superfast Express is a Superfast train belonging to Southern Railway zone of Indian Railways that runs between Ernakulam Junction and Sir M. Visvesvaraya Terminal in India.

Initially, there were two Ernakulam–Sir M. Visvesvaraya Terminal Superfast Express services. The first service was numbered 12683 / 12684 and the second service was numbered 22607 / 22608. The first service was started on 3 November 2005 and the second service was started on 24 July 2011. Both services initially terminated at Bangalore City railway station and were named as Ernakulam–Bengaluru City Superfast Express but to de-congest Bangalore City these trains were later shifted to Banaswadi and renamed as Ernakulam–Banaswadi Superfast Express on 1 September 2017. In 2021, a decision to combine both the Banaswadi expresses and run it as a triweekly service between Ernakulam Junction and Banaswadi via Krishnarajapuram was taken.
